Ctrl Alt Numpad 0 keeps moving my object?
The answer was to first select the camera and press Ctrl+Numpad 0 and then perform the Ctrl+Alt+Numpad 0

User CD38 on http://blenderartists.org/forum/archive/index.php/t-78116.html explains:


  I'm pretty sure you made the body into the camera at some point with
  an accidental Ctrl-zero when it was selected. You need to be careful
  with those Numpad-zero commands. Here they are:
  
  
  zero alone: changes the viewport so you're looking
  through the active camera. ("I wonder what the camera's seeing?")
  Ctrl-alt-zero: moves the camera to match the current 3D
  viewport. ("I like this angle; let's put the camera here.")
  This is why your humanoid is jumping around and looking
  inside itself. Very mind-bending.
  Ctrl-zero : makes the selected object into the active
  camera. Anything can be a "camera." In this case it's your
  humanoid object. This is poorly documented and seems to cause
  all kinds of grief because it's an easy misstep.
  
  
  Select the real camera with the RMB and do Ctrl-zero and all should be
  well.
